With Sigma 1.6 achromatic and quickly processing in LR.
Accidentally had on cam flash on but it worked out nicely. Next time I'd probably do flash exposure comp -1.
Still learning to judge placing the camera the correct working distance from the subject for each filter so the autofocus works well.
All in all it works!
